Similiar queries returning different results - should report dup columns

[mroberts]

Similiar queries returning different results. Both queries should report,
duplicate columns.

mysql> desc qastringtest1;
+-------+------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+------------+------+-----+---------+-------+
| c1 | char(1) | YES | | NULL | |
| c2 | char(8) | YES | | NULL | |
| c3 | varchar(1) | YES | | NULL | |
| c4 | varchar(8) | YES | | NULL | |
| c5 | char(5) | YES | | NULL | |
+-------+------------+------+-----+---------+-------+
5 rows in set (0.04 sec)

mysql> desc qastringtest2;
+-------+------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+------------+------+-----+---------+-------+
| c1 | char(1) | YES | | NULL | |
| c2 | char(8) | YES | | NULL | |
| c3 | varchar(1) | YES | | NULL | |
| c4 | varchar(8) | YES | | NULL | |
| c5 | varchar(5) | YES | | NULL | |
+-------+------------+------+-----+---------+-------+
5 rows in set (0.00 sec)

mysql> select * from qastringtest1, qastringtest2 where
qastringtest1.c4=qastringtest2.c4;
ERROR 138 (HY000):
The query includes syntax that is not supported by InfiniDB.

                                                                 Restructure
the query with supported syntax.
mysql>
mysql> select * from qastringtest1, qastringtest2 where
qastringtest1.c5=qastringtest2.c5;
Empty set (0.14 sec)

Notice the second query is comparing a char to a varchar.

It returns the wrong resutls (0 rows), but should report duplicate column, as
should the first or not supported since it's comparing a char to a varchar.

create table qastringtest1 (c1 char(1), c2 char(8), c3 varchar(1), c4
varchar(8), c5 char(5)) ENGINE=infinicb;
create table qastringtest2 (c1 char(1), c2 char(8), c3 varchar(1), c4
varchar(8), c5 varchar(5)) ENGINE=infinidb;
insert into qastringtest1 values ('a','abcdefgh','b','ijklmnop','1234 ');
insert into qastringtest2 values ('a','abcdefgh','b','ijklmnop','1234 ');
insert into qastringtest1 values ('c','aaaaaaaa','d','bbbbbbbb','5678 ');
insert into qastringtest2 values ('c','aaaaaaaa','d','bbbbbbbb','5678 ');
